K1800G application field and working principle

Thyristors are semiconductor switches used in medium- and high-power applications. They consist of four layers of alternating P-type and N-type materials, hence they can be used in a wide range of applications. K1800G is one of the most popular Thyristors which can be used in various industrial and domestic applications.

Application field of K1800G

The K1800G is suitable for heating and air-conditioning systems, rectifiers, switch mode power supplies, synthetic furnace systems, and various industrial control systems due to its excellent ruggedness, fast response time, high voltage, and low current. The K1800G is also used in domestic applications such as electric ovens, microwaves, and toaster ovens. Its high voltage capability ensures reliable and long-life operation in these applications.

Working Principle of K1800G

The K1800G is a four-layer device with alternating p-type and n-type layers. It is a four-quadrant device with its anode (A) and cathode (K) terminals connected to the applied voltage. When the applied voltage is above a certain threshold, the electrons and holes can be injected from the n-type to the p-type material, triggering the flow of current. As the current increases, the device starts to conduct more current, resulting in an increase in the collector current. The collector current is then connected to the load, allowing current to flow through the load.

The K1800G can be used in both AC and DC applications, but it is more commonly used in AC applications. When used in AC applications, it acts as a switch, allowing the voltage to be turned on and off at a certain frequency. This can be used for various purposes, such as controlling the speed of motors or for controlling the intensity of lighting.

The K1800G is a highly reliable device with excellent performance capabilities. It can operate at a high frequency and withstand extreme temperature changes. It is also able to operate in harsh environments such as high humidity, dust, and shock. It is also resistant to thermal runaway, which makes it a safe choice for industrial applications.

Conclusion

K1800G is a popular Thyristor used in a variety of applications. It is a very reliable device due to its four-layer structure and fast response time. It can operate in a wide range of frequencies and can handle extreme temperatures. It is also resistant to thermal runaway, making it a safe choice for industrial applications. Thus, the K1800G can be a great choice for a variety of applications.
